Silverstream: A fully decentralised music streaming platform

Installation

Silverstream requires Python 3.7+ with the libtorrent library, as well as the libmpv1 package from your local package repository. The dependencies can be installed from the Debian repositories:

sudo apt install -y python3.7 python3-libtorrent libmpv1

Or from source:

# Python 3.7  (https://docs.python.org/3/using/unix.html#building-python)
sudo apt build-dep -y python3
wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz
tar xf Python-3.7.1.tgz
cd Python-3.7.1
./configure --enable-optimizations
make -j$(nproc)
sudo make altinstall

# Libtorrent  (https://dev.deluge-torrent.org/wiki/Building/libtorrent)
sudo apt build-dep -y libtorrent-rasterbar
wget https://github.com/arvidn/libtorrent/releases/download/libtorrent_1_1_11/libtorrent-rasterbar-1.1.11.tar.gz
tar xf libtorrent-rasterbar-1.1.11.tar.gz
cd libtorrent-rasterbar-1.1.11/
PYTHON=$(which python3.7) ./configure --enable-python-binding --with-libiconv --disable-debug
make -j$(nproc)
sudo make install
sudo ldconfig

The libtorrent version from the Debian repository doesnt't seem to play nicely with Python 3.7, so please check the installation:

python3.7 -c "import libtorrent; print(libtorrent.version)"

After installing the dependencies, the application can be installed using pip:

python3.7 -m pip install --upgrade https://git.caspervk.net/caspervk/silverstream/archive/master.tar.gz
